Primal Pet Foods Gently Cooked line, which features six recipes for dogs and cats, will only be available in the freezer section at neighborhood pet stores. The Gently Cooked meals are prepared with the sous vide cooking method, which means the food is slowly cooked at a low, controlled temperature. Primal mixes the fresh, high-quality ingredients together and then, vacuum seals them in a food grade pouch that is placed in a warm water bath for several hours. Since the ingredients are lightly cooked in their natural juices, the meals are very palatable for dogs and cats.
